Description

Technical Field

[0001] The utility model relates to the technical field of mining mobile train equipment, in particular to a track clamping device. Background Art

[0002] In recent years, the application of close-range fluid supply and close-range power supply technology in coal mining faces has increased, the load capacity of equipment trains supporting comprehensive mining faces has continued to increase, and the length of equipment trains has continued to increase. This has made the traditional method of transporting working face equipment by winch wire traction mining narrow-gauge vehicles increasingly unsafe.

[0003] After searching, the Chinese patent application No. 201920310588.9 discloses a hydraulic self-moving equipment train, including a guide track, a car body overlapped on the top of the guide track, a frame is arranged on the top of the car body, the front and rear sides of the right side of the bottom of the car body are movably connected to the front and rear sides of the inner wall of the guide track through push jacks, the front and rear sides of the right side of the car body are fixedly connected with lifting jacks, the right side of the lifting jack is fixedly connected with an adjustment ear, the front and rear sides of the right side of the car body are fixedly connected with connecting rods, and a guide wheel is arranged on the bottom of the car body, and the guide wheel slides on the top of the guide track.

[0004] The hydraulic self-propelled equipment train in the above-mentioned patent has the following shortcomings: the device realizes the distributed alternating forward movement of the vehicle body and the track by changing the relative size of the friction between the vehicle body and the ground and the friction between the track and the ground. When the vehicle body needs to move forward, the vehicle body is lifted by lifting the jack to reduce the friction between the vehicle body and the ground, and the track is pressed down by lifting the jack to increase the friction between the track and the ground, thereby realizing the forward movement of the vehicle body; however, in actual use, continuous alternating movement is required between the track and the vehicle body. In the case of a single movement, the moving distance of the vehicle body and the track is short, which is not conducive to the use of the overall device. Utility Model Content

[0034] Embodiment 1;

[0035] The clamping assembly 2 includes a supporting frame 201 and a protective top cover 215 fixedly connected by bolts, and mounting connecting plates 202 are welded to the bottom of both the front and back sides of the supporting frame 201, and rotating mounting shafts 204 are rotatably installed at both ends of the mounting connecting plates 202. A limiting ring is fixedly installed at the top end of the rotating mounting shaft 204, and the bottom end of the rotating mounting shaft 204 passes through the mounting connecting plate 202 and extends downward, and a movable clamping wheel 205 is rotatably installed at the extended end.

[0038] The bottom end of the supporting frame 201 is equidistantly fixedly connected with a plurality of supporting frame plates 218, the upper surfaces of the plurality of supporting frame plates 218 are fixedly connected with a positioning mounting frame 219, two clamping hydraulic cylinders 220 are symmetrically installed inside the positioning mounting frame 219, and a controller 216 is fixedly installed at the top end of the positioning mounting frame 219, and the controller 216 controls the extension and retraction of the clamping hydraulic cylinder 220.

[0042] Embodiment 2:

[0043] On the basis of the first embodiment, some structures are added to further enhance the stability between the clamping assembly 2 and the mine car track assembly 1.

[0044] A plurality of mounting pins 208 are welded at equal intervals on the top of the mounting bracket 206, and the mounting pins 208 are fixedly mounted on a limiting connector 209 by nuts and washers.

[0045] A connecting shaft 211 is fixedly installed inside the tooth arm gear 210. The top of the connecting shaft 211 passes through the top groove wall of the rotating installation groove and extends upward. A hexagonal clamping column is fixedly connected to the top of the extended end, and a friction wheel 212 is fixedly installed outside the hexagonal clamping column.

[0047] Two stabilizing baffles 217 are fixedly connected inside the mounting bracket 206 . The stabilizing baffles 217 are arranged on both sides of the connecting slide arm 214 to improve the stability of the mounting bracket 206 and facilitate the sliding of the connecting slide arm 214 .

[0048] When this embodiment is in use, on the basis of the first embodiment, when the auxiliary boss 107 is inserted into the clamping slot 222, the friction arm 213 is engaged with the friction wheel 212, and the two are tightly fitted. The fitting surfaces of the friction wheel 212 and the friction arm 213 are both set as friction surfaces, and the connecting shaft 211 is fixed by the static friction force between the two, and then the tooth arm gear 210 is fixed and cannot rotate. With the cooperation of the mating tooth arm 105, the tooth arm gear 210 is relatively fixed to the mating tooth arm 105, and the static friction between the auxiliary boss 107 and the clamping friction strip 223 is used to fix the clamping assembly 2 and the mine car track assembly 1 relatively.
